Why do we want to measure the
properties of the body? What good will it do us to know these
things? Why should we care about the properties of the body?

Knowing the properties of the body
opens up a world of possibilities. Using the knowledge of these
properties allows us to design treatments and special tools to be
used on the body. It also will allow the design of applications
to be used inside the body, like artifical hearts and valves or
internal rods and screws to
help support broken bones. Leg braces can also be
designed when the stresses, strains, and other properties of the
legs are known.

Knowing the properties of the body not only allow us to desing
equipment, it also allows for the creation of mathematical models
that describe the motion and the properties of the body depending
on ceartain variables. Some examples of these models can be seen
in the reference
articles.
